' PERMUTATICN LOCK. I

Application filed January 5, 1923. serial' No. e1o,s3e.

' This invention relates to a permutation lock which is mainly designedhfor motor vehicles, though it may be used for other purposes, the general object of'the invention being to provide means for preventing' an unauthorized person from completng the ignition cirouit to a motor or other eleotrical device and also for shutting oli the fuel line to the motor.

A further object of the nvention is to provide a combination look for the device with means for changing the combination 'whenever desired This invention also consists in certain other features of construction and in the combination and arrangement of the several 'parts, to be hereinafter fully described, illustrated' in the accompanying drawings and specifically' pointed out in the appended claims.` i i i In describing my invention in detail, reference will be had to the acoompanying drawings wherein like characters denote 'like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the invention with parts in section.

Figure 7 is a: transversecsection on line 7-7 of Figure l.

Figure 8 is a transverse section on the line 8-8 of Figure l.

Figure 9 is a side elevation of the eXterior of the case.

Figure 10 is a side elevation, partly n section of the band carrying the numerals for the combination disk.

Figure 11 is a side elevation of one -combnation disks;

Figure 12 is a. lon itudinal section through the disks showing the manner in which they are fitted together.

Figura 13 is an 'end elevaton of the mere here shown in Figura 124 of the Figure`14 is a perspective View i of the looking bolt and sleeve therefor and I Eigure 15 is a diagrammatic View of the wrng system. r In these views 1 indicates a casing which is suitably secured to the dash 2 of a motor vehiole. Thefront of the oa sing is forme'd by' a door 3 which is hinged at one end and is provided with a lock 4: at its other end. This door is provided with a slot 5 and a window 6. A supporting frame 7 is arranged in the casing and a bolt 8 is slidably supported by said franie. This bolt carries a pin 9`which projects through a slot 10 in the frame and a spring 1 1 has one end fastened to' the pin and its other end to a part of the frame and tends to hold the bolt in its forward or unlocking position. The oombination discs 12 are associated with said bolt and these discs 'are arranged on a sleeve 13 'which is` sup:-

ported in 'the' france and 'is 'held against movement therein. The 'discs are provided wth key-ways 1 1 and the sleeve is provided with a key-way 15 to permit the passage of u the spring latch 16 on the bolt. When the key-ways in the discs are -out of alignment with that in the sleeve'the bolt is prevented from being moved and is held in looking position until the discs are moved to place their key-ways in alignnent with each otherand with that in the sleeve. Then the bolt can be moved to unlockng position. The bolt is provided with a recess 17 to receive the head of the spring latch and said head isbeveled 19 do not eXtend entirely through the third p disc and said third disc is provided with a recess 20 for receiving the end of the bolt and the 'head of the lat-ch when' the bolt is in looking position. The 'discs 'fit snugly between the uprights of the supporting frame and thus the spring latch and the key ways are hidden from View at all times so that if a person should gain access to the interier of the box he would stllbe the spring latch at thebeginning ofthe lock- The combination i figures 7 are carried by the bands 22 which are placed ing movement.

on the dscs and are held thereon by the screws 23 and by the tongues 24 tting in the grooves' 25 inithediscs. Thus by removing the discsfromthe sleeve and changing 'the position of the hands any desired combination can be set up for placing the discs in unlocking :position:` The dscs will pro ject through the window '6 in the door so that they can be easily rotated. Thebolt is held in looking position by a `latch 26 engaginga notch 27 in the bolt, said latch being carried by a bar 28 which has one end projecting through the door where it receives a knob 29 so that the bar'can be manually "dle 30 on the bolt projects through the' slot 5' and this" handle has a knob 31 thereon. Thus the bolt can be actuated by hand with out opening the door. This handle passes through a slot 32 in` one arm of a bell "crank lever 33 which is pivoted to the supportingframetand` the other arm `has a curved slot 34 therein which engages a pin 35 which is adjustably mounted on* a shaft 36 which'is rot-atably mounted in the supporting 'rame and which passes through a hole in the bottom of the casing where it is connected with the stem of a valve 37 which is located in the fuel line ot the vehicle. A rod 38 connects the bolt with a slide 39 which is mounted in guideways-40 in the back of the casing. This slide carries the i double contacts 41 andthe single icontacts 42 which areadapted to' engage the cent-acts 43, 44 and 45 in the casing. -The contact 41 is connected with the ignition line as is also the contact 44 so that when these two contacts are in engagement the ignition. line is completedwhen the ignition switch is turned i on.`j The contact 43 is connected with the circuit of an alarm 46 so that whenthe contact 441 engages the contact 43 the alarm circuit will be closed when the ignition switch is moved to closed` position. The contacts 42 and 45 are located in the magneto circuit.

From the above it will he seen that when the driver leaves his car and wishes to i lock the same it is simply necessary for him to move the bolt toward the right by the handle so as to cause the bell crank lever 33 to close 'the fuel line by means of the valve 37 and to break the ignition circuit by means of the slide ;39. This movement of the' slide also closes the circuit to the alarm 46 so 'that when theignition switch is turned the alarm will' be sounded. The

rocked to release the latch 26. A han:

bolt will be held in its looking position and against the action of the spring by the looking` means '26 and 28. As before stated the t'ormation of the latch 26 on the bolt will permit the same to be moved to its looking position `irrespective of the position of the combination disc but the bolt cannot be moved forw'ardly until the discs are in a position with their key-ways in alignment with the key-way in the sleeve. When the driver wishes to use the car again he must first set thediscs in their proper order to place their key-ways in 'alignment with the key-way in the sleeve and thenhe releases 'the latch 26 by turning the sha-ft 28-by means of the knob 29. The spring then moves the bolt forwardly so as to reset the ignition circuit and open the fuel line.

It is thought from the foregoing` description that the advantages and novel features of my invention will be readily apparent.

`I desire it to be understood. that l' may make'changes in the Construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope ofthe appended claims.

What I claim is`:- l i ]..,A lock of the class described including a housing, a supporting frame arranged withinthe housing, a sleeve carried by the supporting frame having a key Way, a plu- ,rality of disksrotatably mounted upon the sleeve and each having a key way adapted to be aligned with the key way in the sleeve, a sliding bolt having one end recessed and movably mounted in 'the sleeve, means normally urging the bolt toward an unlocked position, a spring latch carried by the bolt, a head on one end of the latch formed with a beveled face, manual means for moving said bolt to a lockingpositon and means ou one of said disks cooperating with the head of the latch Whereloy` upon movement of the bolt the latchwll beforced into the bolt recess Whereby said bolt may be moved to a looking position regardless of the position ot' the keyways, and another of` said disks being formed in onefface with an annular recess adapted to receive the head of the latch when the bolt is moved to a locked position to prevent movement of said bolt toward an unlocking position untilthe key ways in said sleeve and disks have been moved, to aligning positions.

2. A lock of the class described including a housing, a supporting frame in the housing,fa sleeve carried by the supporting frame having a longitudinal key way, a plurality of disks mounted for rotation upon the sleeve and having key ways adapted tobe aligned with the key way in the sleeve, a i locking bolt slidably mounted within said sleeve and having a recess in one end, a
